Batch script adjusting Aruba Switch configuration and download it - batch-file

Question

I've made a script that'll change the configuration and downloads the configuration of an Aruba 2530 switch, but it doesn't work all the time. How can I run the ip ssh filetransfer command from within the batchfile so I can automate things?
** config2530.bat **
#echo off
set /p USERNAME="Username? "
set /p PASSWORD="Password? "
for /f "tokens=*" %%i in (switchlist.txt) do (
echo plink -batch -ssh -l %USERNAME% -pw %PASSWORD% %%i -m config.txt
echo pscp -scp -pw %PASSWORD% %USERNAME%#%%i:/cfg/running-config d:\%%i.cfg
echo plink -batch -ssh -l %USERNAME% -pw %PASSWORD% %%i -m exit.txt
)
** config.txt **
config
timesync sntp
sntp unicast
sntp server priority 1 10.36.8.11
time daylight-time-rule western-europe
time timezone 60
write memory
ip ssh filetransfer
exit
exit
** switchlist.txt **
10.36.1.101
10.36.1.102
10.36.1.103
... etc. etc.
** exit.txt **
config
tftp
exit
exit
The issue is that I can't have plink run the commands from the text files with out "ip ssh filetransfer". I've tried enabling filetransfer using:
plink -ssh -l {username} -pw {password} {ipaddress} (config; ip ssh filetransfer)
but this gives:
Keyboard-interactive authentication prompts from server: ------------------
-Access granted. Press Return to begin session.
End of keyboard-interactive prompts from server ---------------------------
SSH command execution is not supported.
Without SSH filetransfer enabled I can't run config.txt or download the configuration from the switch. When I use Putty and manually enter the command "config" followed by "ip ssh filetranser" and then run the batch-file it'll do whatever I need it to do. I
